The texture development of {1 0 0} 〈0 0 1〉 and {1 1 0} 〈001〉 preferred orientations in Fe–Ga sheets annealed under a sulfur atmosphere and the surface segregation of sulfur were investigated. The two fitted S 2p 3/2 peak positions at 161.46 and 163.06 eV by XPS represent the presence of iron sulfide on sheet surfaces. The selective growth of (1 0 0) and (1 1 0) grains was achieved through controlling the segregation of sulfur by annealing in quartz ampoules with varied sulfur content and varied annealing times at 1200 °C.
